Mark Anthony Todd was born October 7, 1910 in Cleveland, Ohio. As he grew up he became a pacifist and went on to become a freelance reporter in the 30s. On his fist assignment Todd was sent to Japan were he found a race of super-intelligent Skull-Men. They accepted Todd and taught him occult secrets and gave him a burning mask. In return for their kindness and he vowed to the Skull-Men to be a beacon of hope and justice as the Blazing Skull. Todd then went to Germany where he joined an anti-nazi movement. He however was captured by Nazi agents and was brought before Adolf Hitler. He somehow managed to escape and traveled to London where he saved Winston Churchill's life from Nazi mercenaries.
Todd then returned to the United States and resumed his reporter job with the Daily Globe. Still using the guise of Blazing Skull he continued to fight threats such as Big Joe and Doctor Fear. In 1942 he joined the Invaders to battle Battle-Axis. After the fight with Battle-Axis he joined the Invaders and other wartime heroes in a battle behind enemy lines.
In January of 1945 the Skull returned to New York and foiled a plot by Nazi agents as they tried to blow up the Statue of Liberty. Their leader, the Masked Raider fled the scene, but vowed to return to make the Skull pay for his interference. Wanting more information on the story his editor at the Daily Globe sent him to London where he encountered the Iron Cross, who was filming a missile test. As the Skull and Iron Cross began to fight, Union Jack joined the Skull and the two managed to cause the Iron Cross to retreat to Germany. After the battle Union Jack helped the Skull by contacting the Destroyer in Germany. After that Jack flew the Skull behind enemy lines where Skull parachuted into Germany. The Destroyer greeted the Skull, and the two were found by Nazi soldiers. To deceive the Nazis, the Destroyer knocked the Skull unconscious and handed him over to the Nazis. Todd was then brought before Iron Cross and Nazi scientists who revealed their plan to use homing beacons in order to tactically bomb the United States. During this time the Destroyer was caught sabotaging the missiles. He was brought before the Iron Cross and managed to free the Skull who along with the Destroyer managed to stop the Nazis and blow up the Iron Cross. Todd returned to America and gave his story to his editors, who couldn't believe how lucky he was. However the threat wasn't over yet when the Masked Raider returned and tried to bomb the White House. Todd stopped the Masked Raider, who turned out to be a radio show host. However the missiles had been launched and the Skull commandeered a prop plane and rammed it into a missile, saving the White House.
After the war had ended Todd became a newspaper columnist and urged the American people to support more military action overseas. Realizing that he had not aged in decades he returned to being the Blazing Skull. He used various aliases such as Steve Valiant and Richard Stetson. There are little or no records of his activities during the following decades. Eventually he was declared dead.
During the Kree/Skrull War Rick Jones powers manifested themselves and he manifested various golden age superheroes. Among them was the Blazing Skull. The Skull managed to fight off several Skrulls and Kree soldiers until Ricks' powers failed and the heroes were sent back to wherever they originated from.
Todd then recently showed up in the Middle East and taken into custody of a terrorist known as Malik for years. He was ritualistically beaten and tortured each day by urinating on him and beating him senseless. One day U.S.Agent aka John Walker freed Todd from his prison and asked him to join the new Invaders alongside Spitfire, Union Jack, and Tara. Todd accepted and aided the Invaders in an attack involving Atlantis. The team aided Namor and added him to their ranks. Together the Invaders invaded Mazikhandar and came into conflict with the Avengers. The Skull recognized Captain America and greeted him as a fellow Invader, forming a somewhat steady alliance between the New Invaders and the Avengers. After the skirmish a cruel politician shot the current leader of Mazikhandar and took control of the country. However the Thin Man showed up and killed the politician. Mazikhandar became a protectorate of Atlantis and the Invaders added Thin Man to their ranks. The Two teams parted ways and left each other on semi-good terms.
Weeks later several cloned terrorist creatures called Pterorists attacked the Jim Hammond. Luckily the Invaders arrived and saved Jim. However the true motive of the Invaders saving Jim was to ask for the V-Battalions help. Jim accepted their help and along with the Thin Man's ship the Infiltrator, its captain the Fin battled Axis Mundi. During the battle against Axis Mundi aboard the Infiltrator the Nazi the Gotteskrieger impaled the Skull with a spear and ripped off his head. During the battle fellow Invaders fought Axis Mundi agents, Baroness Blood, Warrior Woman, and Meranno. During the battle the Skull managed to pick himself up and revive himself even without his head. The Skull was a major factor in the Invaders winning the battle when the Skull took down the Gotteskrieger.
Days later the Destroyer and his friend Nigel encountered Vampires in Germany who were sent after a small town by Baroness Blood. The Invaders learned of this and sent Union Jack, Spitfire, Tara, and Jim Hammond who eventually defeated Baroness Blood. Weeks later Baron Strucker, the leader of Hydra sent a mind controlled Wolverine to attack the Invaders. During their first clash the Skull apparently recognized Wolverine and called him "Charlie", whether they truly have met before or it is just the Skulls mental instability is unknown. However during a clash between the Skull and Wolverine, Logan sliced off the Skulls left arm and leg. U.S.Agent then told the Skull to heal and managed to stop Wolverine before he could kill Namor. As the Skull flew the injured Invaders away Logan was sent on another mission by Hydra.
Days later the Thin Man managed to capture Agent Axis and started to psychically torture them in order to get information from them. While the Thin Man tried to get information from Agent Axis, U.S.Agent and Blazing Skull watched Union Jack sketch a nude Tara. Enraged at their attitude Hammond and Spitfire chewed out Skull and Union Jack. However in order to "help" Jack with his sketches the Skull started to strip, showing his naked skeleton body. Grossed out Hammond and Walker forced Todd to redress himself. Captain America then tried to shut the Invaders down by infiltrating the Infiltrator. The Captain and the Thin Man fought for a few minutes before becoming aware of a plot by Meranno. The team along with Captain America intercepted Meranno and a fight broke out on a secluded island. There the team learned that Tara was an Axis Mundi sleeper agent. During the fight that followed Jim Hammond sacrificed his life in order to save Tara. However Tara became comatose and the Invaders continue to search for a way to save Tara from her comatose state.
Recently, the Skull joined the 50 State Initiative and was contracted by Iron Man to work on the new Defenders team.
